4 - (4/n) + (5/n) + (15/(3n^2))


                Please notice how I rewrote your post using parentheses.

                I did it to show different parts of formulas in clear way. 


There is a constant term of 4, and 3 other terms, containing  n  and  n%5E2  in their denominators.


These three terms tends to zero as n tends to infinity.


THEREFORE, the limit is 4 when n approaches  infinity.

Is something that is unclear to you in my explanation ?


                Next time, as you post to this forum, use parentheses to show clearly different parts of the formulas,
                their numerators and denominators.


                Otherwise, your posts will be UNREADABLE at this forum.
